Abstract
The invention provides a bag type air spring. The air type air spring comprises an upper winding plate, an air bag, one or more girdle rings and a lower winding plate. The air bag is provided with a waist portion, wherein the girdle rings are arranged on the outer side of the waist portion and are exposed out so as to squeeze the air bag. According to the bag type air spring with the girdle rings externally arranged, after the air bag is vulcanized, the girdle rings are mounted. Therefore, the structure of a mold is simplified, the vulcanization technology is simplified, and the yield is improved. Meanwhile, the externally-arranged girdle rings are not prone to loosening due to selection of steel rings, and the failure rate can be greatly reduced. The bag type air spring is wide in application and can be suitable for two-bend or three-bend or four-bend air springs.
Description
Technical field
The present invention relates to automobile shock, industrial cushion technique field, specifically, the present invention relates to a kind of bellow type air spring.
Background technique
After the girdle ring of existing bellow type air spring is bead winding by mould directly and waist (rubber adds tyre cord) sulfide.
Fig. 1 is the internal structure schematic diagram of a kind of bellow type air spring of the prior art; Fig. 2 is the structure for amplifying schematic diagram of the bellow type air spring in Fig. 1 at A place.As shown in Figure 1, its structure of existing bellow type air spring comprises roll bending 1, air bag 2, lower roll bending 4.Wherein air bag 2 comprises built-in girdle ring 3(steel traveler).Upper roll bending 1 has air inlet screw 5 and is provided with connecting screw rod 6, lower roll bending 4 is then provided with connecting screw hole 7.
As shown in Figure 2, this girdle ring 3(steel traveler) add tyre cord from the waist 8(rubber of outside and air bag 2) be fixed together by sulfuration.Due to the canoe that steel traveler is generally 5 row × 6 layer, steel traveler in using process may be caused like this to loosen and to lose efficacy; And causing Mold Making difficulty to strengthen due to steel traveler sulfuration together with rubber, tyre cord, sulfuration reject rate is high, technique relative complex.
Summary of the invention
A technical problem to be solved by this invention is to provide a kind of bellow type air spring, and girdle ring is not easily loosened, and reduces failure rate.
Another technical problem to be solved by this invention is to provide a kind of bellow type air spring, can simplify mould structure and sulfuration process, promotes up-to-standard rate.
For solving the problems of the technologies described above, the invention provides a kind of bellow type air spring, comprise roll bending, air bag, girdle ring and lower roll bending, described air bag has waist; Wherein, the quantity of described girdle ring is one or more, is arranged at the outside of described waist and exposes, by described air sac pressing.
Alternatively, the material of described girdle ring is steel ring.
Alternatively, the material of described waist is rubber after sulfuration and tyre cord.
Alternatively, described bellow type air spring is the bellow type air spring of two songs, three songs or four songs.
Alternatively, described upper roll bending have air inlet screw and be provided with connecting screw rod.
Alternatively, described lower roll bending is provided with connecting screw hole.
Compared with prior art, the present invention has the following advantages:
The present invention proposes can the bellow type air spring of external girdle ring, makes bellow type air spring after air bag vulcanizates, can install girdle ring again.Make that mould structure simplifies, sulfuration process also simplifies like this, up-to-standard rate improves.Meanwhile, external girdle ring, by selecting steel ring, not easily loosens, and greatly can reduce failure rate.
Applicability of the present invention is extensive, is applicable to the bellow type air spring of two songs, three songs or four songs.
Accompanying drawing explanation
The above and other features of the present invention, character and advantage become more obvious by passing through below in conjunction with the description of drawings and Examples, wherein:
Fig. 1 is the internal structure schematic diagram of a kind of bellow type air spring of the prior art;
Fig. 2 is the structure for amplifying schematic diagram of the bellow type air spring in Fig. 1 at A place;
Fig. 3 is the internal structure schematic diagram of the bellow type air spring of one embodiment of the invention;
Fig. 4 is the structure for amplifying schematic diagram of bellow type air spring at B place embodiment illustrated in fig. 3.
Embodiment
Below in conjunction with specific embodiments and the drawings, the invention will be further described; set forth more details in the following description so that fully understand the present invention; but the present invention obviously can implement with multiple this alternate manner described that is different from; those skilled in the art when doing similar popularization, deduction without prejudice to when intension of the present invention according to practical situations, therefore should can not limit the scope of the invention with the content of this specific embodiment.
Fig. 3 is the internal structure schematic diagram of the bellow type air spring of one embodiment of the invention; Fig. 4 is the structure for amplifying schematic diagram of bellow type air spring at B place embodiment illustrated in fig. 3.It should be noted that bellow type air spring of the present invention can be the bellow type air spring of two songs, three songs or four songs.Therefore, only exemplarily, it is also not draw according to the condition of equal proportion to shown in Fig. 3 and Fig. 4 two bent springs, should not be construed as limiting in this, as to the protection domain of actual requirement of the present invention.
Come together to understand incorporated by reference to Fig. 3 and Fig. 4, it is such as steel ring instead of steel traveler that this bellow type air spring mainly comprises roll bending 1, air bag 2, girdle ring 3(material) and lower roll bending 4, air bag 2 has waist 8.Wherein, the quantity of girdle ring 3 is one or more, determines according to the kind of this bellow type air spring.Such as, for two bent springs, the quantity of this girdle ring 3 is one; For three bent springs, the quantity of this girdle ring 3 is then two; For four bent springs, the quantity of this girdle ring 3 is then three, by that analogy.
After air bag 2 sulfuration completes, one or more this girdle ring 3, by extruding gasbag 2, is arranged at the outside of waist 8 and exposes.The material of this waist 8 is (after sulfuration) rubber and tyre cord, and thus, this girdle ring 3(is as steel ring) installation steps just independent with the sulfuration process of rubber and tyre cord.So just make corresponding mould structure simplify, sulfuration process also obtain simplification.
After girdle ring 3 installation, volume presses roll bending 1 and lower roll bending 4, and owing to being subject to gas pressure when external girdle ring 3 uses, the place hoop that can be automatically found air bag 2 the narrowest is dead.
In addition, for the structure of the bellow type air spring of the present embodiment, upper roll bending 1 has air inlet screw 5 and is provided with connecting screw rod 6; Lower roll bending 4 is provided with connecting screw hole 7.
In sum, the present invention proposes can the bellow type air spring of external girdle ring, makes bellow type air spring after air bag vulcanizates, can install girdle ring again.Make that mould structure simplifies, sulfuration process also simplifies like this, up-to-standard rate improves.Meanwhile, external girdle ring, by selecting steel ring, not easily loosens, and greatly can reduce failure rate.
Applicability of the present invention is extensive, is applicable to the bellow type air spring of two songs, three songs or four songs.
Although the present invention with preferred embodiment openly as above, it is not that any those skilled in the art without departing from the spirit and scope of the present invention, can make possible variation and amendment for limiting the present invention.Therefore, every content not departing from technical solution of the present invention, any amendment done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all fall within protection domain that the claims in the present invention define.
